Jakarta's traffic is NOT the worst, it somehow has a bad rep. Vietnam has by far the worst I have seen. I found it interesting for 2 nights/3 days. Used Uber only and was ok, however on the way back from old town driver got lost and was not a fun experience. It is not unsafe. If female, wear long sleeves and long leggings. People may stare at you if Caucasian and want to take pics taken with you. There is a free bus in downtown that I never found so used taxis and uber. If you have guts for short distances you can take bikes. I did not at the time but not would totally do it only for short distances. Mostly due to the fact that they move quicker. There is also Grab and Go jek. Go jek is the cheapest especially if you top up - 30% cheaper. If you don't it is sometimes cheaper, sometimes same as Grab and Uber.

Are shorts and a polo shirt fine for a guy?

Uber is super easy and cheap here, but the roads are often unpleasantly jammed.

I'm guessing hundreds of thousands have used Uber in Jakarta, and in other Indonesian cities. It's just like using Uber anywhere else. Pretty much straightforward, though pick-up times can get pushed back (traffic).

The airport (CGK) isn't the easiest place to kick off your Uber relationship: best line up for a Bluebird or splash cash on a limo (it won't break the bank).

It's not a resort.

You are not on a beach. Unless it is your goal, I would try to minimize unwanted attention and dressing to blend in is one of such actions.

I personally would recommend to visit Bali or Ubud if you haven't visited in the past. However, if you want to visit Jakarta for any personal reason, you need to visit

below places:

1) National Museum

It is an archeological, historical, ethnological, and geographical museum. When you see it at first time, you will be convinced that it is worth to visit. It is also

well known as Elephant Building because of the elephant statue there.

2) Taman Mini Indonesia Indah

It is short form is TMII. It is located in the eastern part of the city and you will learn Indonesian Culture.

3) The Istiqlal Mosque and The Catholic Cathedral

Istiqlal is the largest mosque in Indonesia. You could say it�s like the Taj Mahal stands opposite the Sagrada Familia.

I wear shorts and a Batik shirt 364 days a year in Indonesia. Unless you're going to a temple, or a wedding, it's not a big deal

Good. It's unbearable wearing pants and long sleeve shirts in Singapore during the day. Jakarta has to be as hot or hotter.

I would not go to Jakarta with high expectations for 3 1/2 days. You'll spend most of your time sitting in traffic waiting to get to your destination. (I've counted myself unlucky many times when I was assigned an Uber car that didn't arrive for 30 minutes as the driver was stuck in traffic making a simple U-Turn to reach my hotel.)

You didn't mention where you're going in Malaysia. It's a large and diverse country. Have you really used up every location of interest? Sepilok Orangutan Rehabilitation Center, upriver Sarawak adventures, climbing Mt Kinabalu, the tea plantations of Cameron Highlands? I'm sure forum members could offer many more suggestions for Malaysia travel that would be more valuable than being stuck in the back seat of a Jakarta taxi.

Totally fine! Unless if you go to a mosque, formal event or nightclub (prepare to dress up).

I always use Uber in Jakarta, very low price, usually they use Google maps/Waze to get you around so usually you get to where you want to go. The only downside is that most Uber drivers don't speak English, so if you can't speak Indonesian it might be too much of a hassle for you.

I have been living in Singapore for last 5.5 years. I wear pants and long sleeves and walk to office every day - 40 min each way. I am still alive, like many other people here.

Blessedly, most of those in Singapore are hardier than you and survive in grown-ups clothes in the city proper. Things might get looser at the weekend and on the coast, but ....

Noone's going to stone you for inelegance. Jakartans are generally tolerant of the ways of foreigners. OK, broad exceptions to that, but fashion faux pas are excused.

And i would defend your right to dress in any way you wish: shorts and all . But you did ask.

The caveat is that it takes a level of insouciance, and wise choices to carry it off. And from your questions, you might be a little short in one or the other of those areas.

Arizona golf course or Fort Lauderdale chic is not a look that travels well.

Hopefully, you at least wear long clothing in sensible fabrics. I don't know how anyone wears wool. Seersucker cotton, cotton, linen and blends of those fabrics are the only sensible choices.

Actually you've missed fabric which is most suitable in tropics - microfiber polyester - so called duo-dry brands. Cotton is the last thing you want to wear when it is 90F with 80% of humidity.

Does anyone have recommendations for drivers/guides for Jakarta? I'll be there for a day while in transit and looking for a tour.
